Alright, I installed ArmA 2 steam bundle. Ran Arma 2 first installed OA PR etc ran them all for first run. Played just regular Arma 2 for a while just fine, but when I play OA after about 5 min of gameplay, it freezes closes then says "Data Error: Cyclic Redundancy Check" I read around the forums but no one has said that the others work just fine or the can run the game for 5 min... I've reinstalled over 5 + times and its really frustrating! I just want a fix...
